Page "Astrology" Paragraph 22

Other important Arabic astrologers include Albumasur and Al Khwarizmi, the Persian mathematician, astronomer and astrologer, who is considered the father of algebra and the algorithm.

The Arabs greatly increased the knowledge of astronomical cycles, and many of the star names that remain in common use today, such as Aldebaran, Altair, Betelgeuse, Rigel and Vega retain the legacy of their language.
